Some important thoughts for System Administrators

  1. Never do something you can't undo.
  2. Always check the backups, never assume they are working. Make sure you can restore from them, too.
  3. Write down what you did, even if you know you will never forget it, you will.
  4. If you do it more than once, write a script.
  5. Get to know your users before there is a problem, then when there is, they will know who you are and maybe have a little understanding.
  6. Remember you are performing a service for your users, you don't own the system, you just get to play with it.
  7. Check your backups.
  8. Never stop learning, there is always something you should know to make your job easier and your system more stable and secure.
  9. Check your backups, again.

Synchronize Folders Between Computers and Drives with SyncToy 2.1

If you have a few different computers and drives, it can be annoying making sure the same data is each one you need. Today we take a look at making folder and data synchronization easier with the Microsoft SyncToy 2.1 utility. You might have a flash drive that you use to carry files and documents from the workplace to your home office and vice versa. Sometimes though, you might forget to copy the files you need over to the drive. With Microsoft’s SyncToy it allows you to easily make sure the data between drives and folders is synchronized everyday. There are a lot of reasons you might want to synchronize folders.

[AIX] How to restart network service in AIX environment?

When network service like telnet connection hangs, then it is possible the inetd subsystem is not working properly. # refresh -s inetd 0513-095 The request for subsystem refresh was completed successfully. If the refresh hangs for some time and comes back with 0513-056 time out waiting for command response, then the inetd subsystem may not be working correctly and should then be killed nicely. Run #ps -ef | grep inetd and do a kill -15 on the process ID on the line that has /usr/sbin/inetd. Once inetd has been killed, type startsrc -s inetd. If inetd starts, try to telnet into the machine. If inetd does not start up successfully, or if telnet still hangs indefinitely, run kill -15 on the PID of inetd again. Back up the original /etc/inetd.conf file to a new file name by typing: # mv /etc/inetd.conf /etc/inetd.conf.backup The original template is in /usr/lpp/bos.net/inst_root/etc/. You can copy it by typing: # cp /usr/lpp/bos.net/inst_root/etc/inetd.conf /etc/inetd.conf Run start...
